广泛分布在大洋海底的铁锰结壳是固体矿产的远景资源。结壳即富含一系列贵金属元素(包括钼),又富集生态学所指的有害元素,尤其是铊和碲。资料显示:结壳中钼和铊含量比沉积岩平均含量高100~120倍,而碲相比高10000倍。因此揭示这三种元素在铁锰结壳中的赋存形式,在地球化学方面和 Iron-manganese crust widely distributed in the ocean floor is a long-term resource of solid minerals. Crusts are rich in a series of precious metal elements (including molybdenum), but also enrich the ecological elements of the harmful elements, especially thallium and tellurium. The data show that the content of molybdenum and thallium in crusts is 100-120 times higher than that of sedimentary rocks, while that of tellurium is 10000 times higher. Therefore reveal the three elements in the ferromanganese crust in the form of occurrence, in terms of geochemistry and
